RINNOL OLGER PREMIUM 15W40

TBN = 10.9
%w Ca= 0.415
%w P= 0.0731
%w Zn= 0.0792

we also have:
% Mg = 0.0009
% molibden = 0.0031
% Boron = 0.0273

Calcium is used as detergent neutralizing additives.
Phosphorus is a part of anti-wear and extreme pressure additives.
Zinc is an element of the anti-wear additive ZDDP.
Magnesium performs washing, neutralizing and dispersing functions.
Molybdenum (molybdenum disulfide) is added to improve protective, antifriction and extreme pressure properties.

In most cases, a boron—based additive has a positive effect on engine operation – it reduces friction, improves engine elasticity, and increases the life of rubbing surfaces.

Detailed comparative analysis

1. Basic specifications and tolerances

Both products have the same SAE 15W-40 viscosity grade and key tolerances for heavy machinery (ACEA E7, API CI-4, Volvo VDS-3, Mack EO-N, etc.). This means that their basic operating properties (viscosity, low temperature) and protection level are standardized to meet these requirements. Replacing one with the other will not cause compatibility or lubrication issues.

2. Base Number (TBN)

• SHPD: 10.7
• RINNOL: 10.9

Comment: The values are almost identical. TBN indicates the reserve of the detergent and neutralizing potential of the oil to combat acids and combustion products of sulfur fuels. Both oils are designed for long service intervals and run on fuel with a high sulfur content. They are completely equivalent in this parameter.

3. Anti-wear package (Zn and P)

• SHPD: Zn = 0.12%, P = 0.11%
• RINNOL: Zn = 0.079%, P = 0.073%

Comment: Here’s the key difference. The first oil (SHPD) contains a significantly higher concentration of the classic anti-wear additive ZDDP (zinc dialkyldithiophosphate). It is a “workhorse” for the protection of friction pairs (camshaft, rocker arms, cylinder walls) under high loads.

The lower ZDDP content in RINNOL oil does not mean worse extreme pressure properties. The manufacturer compensated for this by adding molybdenum (0.0031%). A molybdenum-based additive package (for example, MoDTC) is more modern and effective for:

• Reduction of friction (antifriction effect).
• Increase fuel efficiency (albeit only slightly for viscosity).
• The creation of an extremely durable protective film on the metal surface.

Conclusion: RINNOL uses a more modern and possibly more effective additive combination (Mo + a moderate amount of ZDDP), while SHPD relies on a time-tested high concentration of ZDDP.

4. Detergent-dispersant package (Ca, Mg)

• SHPD: Ca = 0.36%
• RINNOL: Ca = 0.415%, Mg = 0.0009%

Comment: Both oils use calcium as the main detergent (detergent additive), which keeps the products of oxidation and incomplete combustion (soot) in suspension, preventing them from forming sludge and carbon deposits. RINNOL has a slightly higher calcium content and contains a small amount of magnesium, which often works in synergy with calcium to improve its dispersant properties. RINNOL’s washing potential is, theoretically, slightly higher.

5. Additional additives (Boron)

• RINNOL: Boron = 0.0273%

Comment: The presence of boron is a major advantage of RINNOL oil. Boron-containing additives, as you correctly noted, are excellent friction modifiers, increase anti-wear properties and improve the thermal stability of the oil. This is another step towards a modern, highly efficient additive package.
